🇺🇸 Michai Stephens

Michai Stephens is a professional racing in national pro-am multiclass endurance series, where each car is shared between drivers. He holds an FIA Silver grading, which places him among drivers progressing in sportscar racing rather than fully established professionals. Stephens drives for JMF Motorsports, racing GT3 machinery in GT World Challenge America and GT4 cars in GT4 America and IMSA Pilot Challenge, and has also raced single-driver Radical prototypes and production-based GT machinery across 51 starts since 2023.[1]

Stephens won the 2023 GT4 America Silver championship while driving for Conquest Racing and JMF Motorsport. He took the 2026 GT World Challenge America Pro championship with JMF Motorsports after six wins across 17 starts in that series through early 2026. Across GT4 America he has recorded five wins in 15 starts, and in Radical Cup NA, where he races solo rather than sharing, he has won seven of nine races. He holds 18 wins and 31 podiums from 51 starts overall. He is currently racing TC America powered by Skip Barber in 2026, sitting 13th in the championship with two rounds completed so far.[2]

Stephens competes most regularly against established professionals with multiple graded credentials and deeper endurance experience. He runs closely matched with Kenton Koch, a Gold-graded driver who has been a multiple-series champion across GT4 America and GT World Challenge America, and with Alex Sedgwick, a fellow Silver-graded professional. His record also includes victories over Corey Heim and Bubba Wallace, established drivers with extensive NASCAR backgrounds, though these represent single meetings rather than sustained head-to-head competition. His recent wins include the 2026 GT World Challenge America Pro championship and shared victories at Sonoma and Road America with teammate Grenier.
